“…NAA was eminent in its effect particularly the highest on (100 ppm) since recorded the highest mean values of studied traits. The results of increasing flowering parameters owing to Kinetin treatments are in conformity with previous researches (El-Bably et al, 2017;Abou-El-Ghait et al, 2018;Elbohy, 2018;El-Kinany et al, 2019), while the results of increasing flowering attributes owing to NAA treatments are in good accordance with those elicited by earlier studies (Bairwa and Mishra, 2017;Khudus et al, 2017;Sendhilnathan et al, 2017;Atteya and El Gendy, 2018;Dheeraj and Saravanan, 2018;Pahare and Das, 2020;Sekhar et al, 2020).…”

“…It is recognized to promote cell elongation, cell division, elongation of shoot, vascular tissue, photosynthesis, membrane permeability and water absorption also participate in many physiological processes such as delayed senescence, leaf chlorophyll content, induce flowering and boost growth (Heisler and Byrne, 2020). Foliar application of NAA on some ornamental plants have been reported to promote growth and flower yield attributes (Khudus et al, 2017;Sekhar et al, 2020), photosynthetic pigments, total carbohydrate, polyphenols and flavonoids content, antioxidant activity and enhance nutrient status in plant orangs (Atteya and El Gendy 2018), in addition it was found to be preferable to mitigate the damaging effects of salinity (Abou-El-Ghit, 2015).…”

The present experiment was conducted to determine the effect chemical fertilization rates and foliar application of plant growth regulators PGRs (Kinetin or Napthaleneacetic Acid (NAA) and their interactions on growth, flowering, chemical composition of Ervatamia coronaria plants. The plants were fertilized monthly with NPK at the rate of 2, 4 and 6 g pot-1, in addition to the control plants. Plants received the fertilization treatments were sprayed monthly with either Kinetin or NAA at 50, 100 ppm for each one, while the control plants sprayed with tap water. As general, the results indicated that within each level of fertilizer treatments, treating plants with different concentrations of PGRs (Kinetin or NAA) resulted in significant increase in tested vegetative growth (in terms of plant height, number of branches plant-1, leaf area, number of leaves plant-1, stem diameter, root length, fresh and dry weights of leaves, stems and roots), flowering parameters (Viz number of flowers/ plant, fresh and dry weights of flowers), chlorophylls content, total carbohydrates, N, P , K%, total indoles and total phenols, gibberellins, auxins and cytokinins compared to control, with superiority of NAA particularly the highest concentrations (100 ppm) . Under the same level of PGRs raising the fertilization rate caused a gradual and significant increase in all tested parameters compared to control. Based on the results, it can be recommended that for the highest quality growth and flowering parameters of Ervatamia coronaria, the plants could be sprayed with NAA at 100 ppm combined with 6 g pot-1 NPK.

“…Tamil Nadu is the leading producer of jasmine in the country with an annual production of 1,20,750 tonnes from an area of 15,581 hectares and a productivity of 7.75 tonnes ha -1 . The plants, have long woody stem and bold buds with pinkish tinge, which blooms into snow white star shaped flower with 10 petals which are leaner, longer and spread out [2]. Due to the increasing demand for fresh flowers and concrete, the area under jasmine has increased in recent years and efforts are being made to increase the yield by adopting improved cultural practices.…”

Multi nutrient deficiencies in soil have been reported with increasing frequency over the past two decades on a worldwide scale, is considered as an important factor that reduces yield and affects the quality of harvested products. Nutrient cycling and transformation of in soil is influenced by microbes and the availability of organic and inorganic nutrients to plants and microbes can both be controlled through enzyme activities. Keeping this in view a field experiment was conducted at O. Alangulam village of Thiruparankundram block, Madurai district, Tamil Nadu during 2016-18 to evaluate the influence of organic and inorganic sources of nutrients on soil microbial population and enzyme activities and optimize the sulphur requirement of Jasmine (Jasminum sambac) which plays a key role in enhancing the yield and quality of flowers. The significantly higher bacterial population of 124 × 106 CFU g-1 was observed in the treatment that received pressmud as sulphur source @ 60 g sulphur/plant/year along with RDF (recommended dose of fertilisers were applied @ 60:120:120 g of N:P2O5:K2O/plant/ year in the form of urea, SSP and MOP).This was followed by the treatment that received pressmud @ 40 g sulphur/plant/year along with RDF (111 × 106 CFU g-1). Application of inorganic NPK fertilizers without organics decreased the activities of dehydrogenase and aryl sulphatase enzymes. The flower yield hectare-1 ranged from 3.8 to 15.4 tonnes ha-1as influenced by various nutrient sources. Application of RDF along with Gypsum @ 60 g sulphur/ plant/year recorded significantly higher yield followed by the treatment that received RDF along with Pressmud @ 60 g sulphur/plant/year.
